Room Temperature Synthesis and Characterization of Novel Bi(III) Complex with 2-Amino-3-Carbomethoxy-4,5,6,7-Tetrahydrobenzo [B] Thiophene as Potential Antimicrobial Agent

摘要

A novel bismuth(III) complex with 2-amino-3-carbomethoxy-4,5,6,7-tetrahydrobenzo [b]thiophene (ACTT) as a ligand have been synthesized. The novel complex was characterized on the basis of its IR, NMR, elemental analysis and MS spectral data. It was found that the ligand behaves as a monodentate chelating agent and bonds to the metal ion through the nitrogen atom of the amino group to form the [Bi-III(ACTT)(6)]Cl-3 complex. The new complex compound displayed significant antimicrobial activity (MIC = 8-32 mu g/mL) against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Shigella flexneri, Candida albicans, Candida tropicalis and Cryptococcus neoformans.
